power board, power plug or power socket replacement on yoga s1 or any thinkpad?

Q: power board, power plug or power socket replacement on yoga s1 or any thinkpad?

My Yoga S1 has contradictory, intermittent power issues that I'm trying to chase down. Culprits are bad power bric/cord/plug or power socket on mother board or power board that feeds into power button/led on. One day it blacked out and wouldn't restart to hard drive or windows stage. I did get an error code which I can't remember 5100 or 5500 poss?, that seemed to indicate the power board or ribbons to that needed replacement or re-attachment. So fiddled with it and it did fire up in windows all ok. Then ran out of power and died again. power button wouldn't light up. plugging in power unit did light up led as getting charge. Left it overnight and then it miraculously charged up. pushed power button light up twice then nothing. took out power board/detached ribbon, then it fired up to windows, fixed some hd errors and has been restarting without problems. Except now there is no plug showing on battery icon when plugged in. So not recharging but I'm sure the battery is good. And logically, the power brick and plug must be feeding electricity into laptop to get it to recharge enough to start up. So power socket and plug may be suspect with intermittent contact problems. Or the power board somehow is involved in this? I've ordered a new powerboard as easy screw in and cheap. My question about powerboard is does this control ability of plug to charge battery? power brick with new plug is next order from ebay. but the power socket, which seems to be hard soldered to mother board looks more complicated fix. Part is about $40 and might just be simple unsolder and resolder job. Has anyone done this or is it more complex than expected?

So i have a really old computer. The mother board is a Asus M2N MX SE Plus and i'm having problems doing the last step which is plugging in those Power cables to actually turn on the computer. So there's a 2 pin with the label, "Power sw", another 2 pin with the label. "H.D.D Led", another 2 pin with the label, "Power Led" and lastly a 3 pin with the label, "Power Led E". On the mother board, i know where the panel is for these cables but i just don't know where each one goes. There's intotal of 9 pins with 4 on top and 5 on the bottom.

Sorry I don't know the proper terms, but basically the pin inside the jack where the power cord gets plugged into on my laptop was bent so that it's really hard for me to plug in my power cord and have it stay in place. My warranty with best buy has expired, so I need to figure out how to solve this problem on my own. I can't just leave it like this because the cord comes out really easily and I can't continue to work with such a tenuous setup. Anyway, is this just a matter of replacing the entire unit inside my laptop? I know you probably need more information, but I'm not sure what to provide, so please ask any questions. The laptop is a Toshia M-45, about 3-4 years old. Thanks in advance

Hey, About 5 months ago i decided to swap my HDD for an SSD, for some extra speed. However, when opening the laptop i broke the ribbon cable off the power button board. In the last 5 months i tried buying a replacement from ebay. I have bought boards from 3 different sellers, and not one of them worked. They all showed the same behavior; plugging and then unplugging the cable from the motherboard started the computer, and as soon as i put the cable back in, the computer shut down. I used a multimeter to see what was going on, and it turns out the new boards did not switch anything, whereas the original board switched when the button was pushed (of course). Is there a way i can purchase an official replacement?  Thanks in advance!

Finally broke down and started building a new system -
I'm too old to game, this all started out as a home video
project.

Anyway - gathered all my components, now I'm working
to assemble them.

The case came with an Okia Model 500-ATX power supply.
But no wiring schematic.

I'm trying to identify the power supply fan plug - what seems
to be it doesn't at all match the connector on the board.
And I've got that positively identified by the board manual.

The board has a small male 3 pin connection. The only thing I
can find that might be the fan connector coming from the
supply is a small 4 pin plug at the end of 1 of the strings of
drive power harnesses. Nothing tucked up behind the
supply case or anything.

Is that likely to be it? Or would that be for a floppy or something?

I tried to Google for a wiring schematic, but could find nothing.
In fact, nothing much at all on this brand of supply - just
a couple places that sell them. Please don't tell me I got
an el cheapo that isn't worth having!

At the risk of getting ahead of myself, in case I need to adapt
something like that to the different style male connector on the
board, in this case or something else I may find as i progress,
is there some type of source for adapters, or what would I do?

Bear with me, this probly won't be the last question I'll dream up -
just getting started.

While I'm at it - the board manual talks about a conn... Read more

A:New power supply, no schematic, looking for power fan plug.

There are basically two voltages available to you: 5V and 12V. Doesn't really matter where you get it from - some pin on the mobo or some wire from the PSU.

From the PSU the yellow wires are 12V and red ones 5V, black is ground. The fan voltages should be written on the fan itself, the black fan wire is ground, red may be 12V or 5V depending on the fan voltage.

Fan headers on the motherboard should be labelled so, check with a voltmeter what pin gives out what.

Hi JS246 ,
What is the exact issue on the system? Have you checked with another Dell OEM power adapter? Is the current adapter working fine? Is the adapter frayed?
If you have isolated the source to be indeed the dc power cable, then assuming there is no warranty on the machine, you could contact our team to get a quote for a paid service call - http://dell.to/1vnT6CQ
If you are looking to replace the parts yourself, then you could contact a 3rd party Dell parts seller - http://bit.ly/28SYFVc- they ship parts to UK. Or check on Amazon UK - http://amzn.to/28QNXQ0
Write me a private conversation with the service tag and your contact details(Name and Email) for case records.

I have mostly used the Lenovo T series laptops.  At times I would have to unplug the power cord, pull the battery and push down on the power button to discharge power.  When lenoved came out wid models like the T480s that had a built in battery, they added a pin hole on the bottom that would simulate pulling the battery.  I can not locate any pinholes on the Lenovo L580.  Is there a way to discharge the power or simulate pulling that battery on this model?

Hi everyone,  I've had my Yoga 720 for a few months and I have really enjoyed this laptop. I've had a few issues and wanted to reach out to see if it was fixable in setting or something I should reach out to Lenovo directly. Before this, I was using a Mac so this platform is new to me. Any suggestions are appreciated. 1. Power Button: I've noticed that when my screen goes to sleep I've had to push the power button in order for it to 'wake up'. This has not only been slightly irritating but also very slow. I've noticed that it takes a really long time for it to wake up. I was wondering if there was a way for this to be turned off? This way if I open my laptop it goes to the lock screen or if it falls asleep while open I can press a key instead of having to wait for the button to work. I've also noticed it turns the keyboard light on before the screen. not sure if this happens to anyone else too? 2. Key Board: I'm in college so writing papers and forums is an everyday thing for me. Something that has been happening recently is when I'm in the middle of typing, all of a sudden a 'ping' noise sounds and my keyboard stops typing. At first, i thought maybe it was my palm touching the touchpad causing the courser to move to a different area of the screen so I turned the sensitivity down. But this still happens, at times I'm not even touching the pad and the noise sounds and not only am I no longer typing but the course is somewhere different, at ti... Read more

The other day I found that my old Microsoft Display Dock works just fine connected to the second TB3 port. It is able to connect a couple of USB peripherals, and outputs a perfectly fine 1920x1200 image to my Dell monitor.  Great. But: since it outputs only 5V, there's no way it can charge the X1Y3, so for long sessions I might need to connect a charger to the X1Y3.   My question: while the 5V carrying USB-C docking cable from the Display Dock (HD500) is connected to the second TB3 port (i.e. not the DC in port), can I safely connect the official Lenovo charger directly to the TB3 charging port on my X1Y3 to top it off when needed? Or should I expect a bright flash and the smell of ozone? I'm hoping there's some kind of internal protection for these kinds of scenarios, but I hestitate to investigate this through trial and error.

Does anybody know where I can get a replacement power adapter for a Lenovo Yoga 2 11? According to the manual, it should be 45W. It appears that neither the original nor any approve substitutes that are listed on the Lenovo site are available for purchase from Lenovo.  I tried to buy one online but ended up giving my money to an overseas scammer.There seems to be a facsimile available in the States, but reviews say that it is a fire hazard and wrecks computers. I'd like to buy one that works and is safe. This is for my grandson's Lenovo Yoga 2, 11 inch. It was manufactured in 2016. He lost the power supply while it was under warranty only a few months after buying it but the family was moving so they thought it would turn up. It never did.

Hi, My son's Yoga 700-14 2-in1 has developed an unreliable power connection - the USB connector has to be positioned at a very precise angle for the battery to charge.   (For some reason, it's worst when the battery is <20% charged and becomes more tolerant when the battery is fuller - seems wierd but pretty sure it's not my imagination.) Both the cable and the male connector for the supply seem to be in good condition.   There's nothing visibly wrong with the dc port inside the laptop (hard to see but in torch light all pins look intact and not bent), however, I suspect this might be the problem and needs replacing (perhaps a loose internal connection). Has anyone else encountered this problem or done this repair?  It looks easy enough based on photos of the internals - the wiring isn't buried under any other components. Is there a quicker fix that I'm missing?  I guess I'll check some voltages with a meter and that there are no loose connections before ordering a new part. Thanks Stuart

I purchased a refurbished ThinkPad S1 Yoga (20CD-00BYUS) a month ago, from eBay (US-based shop) with guarantee active up to April 2015. Everything was fine and satisfying until yesterday. After a normal shutdown the night before, it won't power on anymore. The battery was still about 50% on the last shut down. If I press the power button (normal press or even more than 5 sec press), the "red i dot" will light for about 4 sec and then off. No noise, no other sound. I tried to push the emergergency reset button as instructed on the manual, but it didn't work.I tried also making bootable USB, but also didn't work.Anyone have idea what I have to do before the ultimate option = send it to the customer service for repair? I read some similar problem in this forum and it seems useful to check the MB cable. Is it true?Will it affect the guarantee? Thank you for your help.

Older Dell Optiplex GX260 tower model. Okay first I extra a harddrive from an HP older system that had just recently crashed. Now I want to read that drive right? I put it in as a 2nd drive in my Dell Optiplex system, set the jumper to cable selected, go into BIOS and select my 1st drive to show it as AUTO. I hit Save changes, upon rebooting it, it gets to the end of logo display and freezes. Weird, never saw that before, I think crap maybe the IDE cable is set wrong or something. I remove the cable and molex plugs from both HDD's after the power is off and set it back to the way it was.

When I reboot I get to the end of the logo again and it freezes and I can't even get into BIOS. Very strange. Well I go back again to check my work and see it is fine with how the IDE cable is sitting and the Molex plug. Now the system won't even power on. The light to the MOBO is on but the system won't start. I undo the front panel and work to see if the cable is worn but it is not and it appears to be fine. The light to the signal will not work to go green at all.

What do you think could be most common issue of this and why? I don't have a multimeter to test the system with and I don't know if it's more than a passing problem. I have never encountered anything like this were a system worked fine then you attempted to just read a 2nd HDD and it started to cascade a bunch of problems to the system.

Any help or ideas are much appreciated, thanks.

It seems X1C6 is limited to 23W/29W TDP, while X1 Yoga Gen 3 is limited to 44W TDP for short and long term bursts.  It makes little sense as physically X1C6 cooler looks bigger thus thould be able to handle longer/harder loads. Can we hope that it will be fixed in the nearest future? Or is there an actual reason for lowering X1C6 TDP, so people who expect 8650U to run at 44W should just look into buying X1Y3?

Many times HW tests from Windows Troubleshooting and Lenovo Vantage - everything OK.  I attached here HWiNFO specification. - Lenovo Thinkpad Yoga 460 (Windows 1709, all current drivers updated - no change with update 1803 - same situation)  The power adapter (and also i use many others - no change) will immediately reduce the processor frequency to a constant of 0.39GHz and using the bounce between 0 - 15% .Reinstall Windows, HW test and drivers etc. everything is OK.  Even no help from Settings - Windows - Options of Power - set min. usage processor 100% - no affects. The problem persists. ..omg... , whats that? Common opening of Explorer, Word, copying etc., and other elementary activities are now a matter of minutes - big loss of performance. Thank for your help

I usually keep my trusty Yoga 3 Pro laptop beside me with the power cord plugged in at night in sleep mode when I close the lid. This morning when I opened the laptop to turn it on, nothing. Did not start/wake, no power LED either white or amber on side. There has been no trauma - water, dropped, etc - it just decided not to wake up this morning and no power LED is especially troublesome. I have tried to hold the power button in for an extended amount of time to see if it would reset itself, but nothing. My first troubleshooting will be to borrow a friend's known-to-be-working Yoga 3 power charger to see if my charger/power cord is defective/died. I doubt that's the problem, but that's the easy first thing to check. Since I bought the laptop from Lenovo in December 2015, I think the warranty is done, but not sure. (Any comments?) If the friend's charger does not power up the laptop, I plan to open up the laptop (first time for this particular laptop although I've opened up previous Thinkpads and other laptops literally hundreds of times) and disconnect the battery, push the power button for 20 seconds or so and see if there's a discharge that may correct the circuitry. I know I have done this successfully with older laptops. However, I know that Lenovo and other manufacturers are hard-wiring components and making it more difficult to work on. So here's my questions: Will a Yoga 3 Pro power on with a functioning power charger connected and the battery disconnected? I... Read more

My S1 Yoga, 20CD-00B1US, is stuck with the screen off and the power LED stuck on. When I try to push or hold the power button it beeps two short beeps and the LED stays solid. I was running the Lenovo Bios Update Software directly from their site. The power cord was plugged in and no other programs were running (aside from background programs). Now it is just stuck like this. Any thoughts or help would be great. I can't even get it to force shut off. Thank you in advance!

So Dell made a really terrible decision.  They have a transparent strip in the power button for an LED light to indicate if the power is on.  A power indicator is a given in any laptop, no matter how cheap it is.  However, Dell in all of it's genius decided to not include an LED bulb on laptops up to the Inspiron 7000 Series, despite leaving a transparent slot for it.  Seriously, what happened to this brand?!?  Do children make these laptops now?
I want to fix this, as my laptop is no longer returnable and a power indicator is absolutely necessary.  So the only thing I can think of is replacing it with one from the 7000 Series somehow (with some help probably).
This is a Dell Inspiron 5559.  I also have an Inspiron 5547.  Not sure which exact 7000 model I should get the part for...
Are they compatible?
Is there an easier way? Like how Fn+H turns on the hard drive indicator?
Thanks.

A:Can I replace a Dell Inspiron 15 5000 Series power board with a Dell Inspiron 15 7000 Series power board?

The systems use different case and mainboard designs -- and may even be made by different companies.  The answer in all likelihood is no.
I don't think Apple has produced a Macbook with a power indicator -- the PC vendors are playing follow Apple.

Two ThinkPad X1 Yoga Gen2 TabletPCs will successfully boot into Windows 10 just fine from a hard poweroff.  But once in windows, if i choose Restart, it will hang at the "LENOVO" BIOS  level boot up logo with "To interrupt normal startup, press Enter".   Stuck at Lenovo BOOT BIOS initialization screen, right before handoff to the Operating System. "To interrupt normal startup, press Enter" At this point, pressing ENTER does not work.CTRL-ALT+DEL causes the screen to change shade for a moment, but effectively does nothing.Changing the UEFI settings to diagnostics results in black screen.Holding the power switch to force a poweroff, waiting a few moments, and then powering on results in a successful windows startup.  DevMGMT.msc does NOT see bluetooth and there is "Unknown USB Device (Device Descriptor Request Failed)" entry under "Universal Serial Bus controllers".  I have run all automatic updates via "Lenovo Vantage" and the manual TPM update.   I can boot into the firmware setup and have had it revert to factory defaults and reverted to factory defaults for all security settings.   I even tried the Win10 repair startup problems, but it says it cannot fix this.   

A:ThinkPad X1 Yoga Gen2 does not Restart, requires hard power off. Stuck at Lenovo boot logo.

It looks to me like you have a faulty hardware issue or a serious driver issue. Try the Lenovo recovery to put the device back to the factory windows install. If that fails, I would think you have a hardware issue.

When plugging in the power adapter, the "charge" light does not come on, nor will the notebook power up. To rule out the HP power adapter I plugged in a Targus universal adapter (with correct polarity) and same result. Same results whether the battery is installed or not. The notebook had been in storage for several months, therefore, no recent changes. Any ideas?
